Abstract

An electrode biasing system was designed, constructed, and installed on the IR-T1 tokamak, and then, the positive voltage applied to an electrode inserted inside the tokamak limiter and the plasma current, poloidal and radial components of the magnetic fields, loop voltage, diamagnetic flux, and ion saturation currents in the absence and presence of the biased electrode were measured. Results of measurements of biasing effects on the plasma equilibrium behavior and edge plasma rotation are compared and discussed.
